Churro Cupcakes with Cinnamon Mascarpone Frosting
Medically reviewed by Christiana George Updated Date: December 17, 2022


I ran across a recipe for churro cupcakes online and immediately thought of the yummy fried pastry, rolled in cinnamon sugar, and filled with warm gooey dulce de leche that one of our Argentinian friends made for us. For Argentinians, they just aren’t churros unless they are filled with dulce de leche. I can agree to that one. I had my fair share of dulce de leche when I visited Buenos Aires two years ago with my husband to visit his family. I think they put it in or on just about anything. It’s good stuff. One day I will try to make some myself, but for now I will continue to buy it at the store. As a busy mom, recipes need to be kept easy.
So anyway, I knew that if I made churro cupcakes, they had to be filled with dulce de leche. I had some left over from my recent recipes, so it worked out good. First I picked out a recipe for the cupcakes. I chose one from Bakingdom-But I didn’t want a cream cheese frosting, so I chose a mascarpone frosting from Martha Stewart You can’t go wrong with Martha.

Ingredients (18 cupcakes)
FOR THE CUPCAKES
- 1 1/2 cups all-purpose flour
- 1 1/2 teaspoons cinnamon
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 (1 stick) cup unsalted butter, at room temperature
- 1 cup sugar
- 2 eggs, at room temperature
- 1 teaspoon vanilla extract
- 1/2 cup milk, at room temperature
FOR THE CINNAMON SUGAR
- 1/2 cup sugar
- 1 1/2 teaspoons cinnamon
FOR THE FILLING
- 3/4 cup dulce de leche
- 1/4 cup sour cream
FOR THE FROSTING
- 1 cup heavy cream
- 8 ounces mascarpone cheese, room temperature
- 1/2 cup confectioners’ sugar, sifted
- 1/4 tsp. cinnamon
Instructions
To make the cupcakes
Preheat the oven to 350 degrees. Line a muffin pan with cupcake liners; set aside.
In a medium bowl, combine the flour, cinnamon, baking powder, baking soda, and salt.
In a large bowl, or the bowl of a standing mixer, cream the butter and sugar together until light and fluffy. Add the eggs, one at a time, until just combined then stir in the vanilla. Sprinkle 1/3 of the flour mixture over the butter mixture and gently stir in until barely combined. Add half of the milk, mixing until just combined. Repeat these steps with the remaining flour mixture and milk, ending with the flour. Do not over mix.
Fill each muffin cup with 2 tablespoons of batter. I used a measuring spoon. Bake the cupcakes for 14 to 16 minutes, or until a toothpick inserted in the center comes out clean. Allow the cupcakes to cool for 2 to 3 minutes, then dip the top of each cupcake into the cinnamon-sugar mixture to coat it. You really have to smush them in there to get it to stick. Allow the cupcakes to cool completely before filling.
To fill the cupcakes
Combine the dulce de leche with the sour cream and mix well. The sour cream makes the dulce de leche less sticky and easier to pipe. Put the mixture into a piping bag or a thick plastic bag with the edge snipped off. Make a hole in each of the cupcakes, making sure you do not go all the way to the bottom. I used an apple corer. It worked quite well. Then pipe the mixture into each cupcake and fill to the top.
To make the frosting
With an electric mixer on medium speed, whisk heavy cream until stiff peaks form (be careful not to overbeat, or cream will be grainy). In another bowl, whisk together mascarpone, cinnamon and confectioners’ sugar until smooth. Gently fold whipped cream into mascarpone mixture until completely incorporated. Use immediately. After frosting the cupcakes, sprinkle a little bit of the left over cinnamon-sugar onto the frosting.

I made a good match with these recipes. The cupcakes were a perfect blend of cinnamon and dulce de leche. And the frosting was like eating a cloud from heaven. It was well worth the extra money for the mascarpone cheese. Just looking at this picture makes me want to lick the screen. I will go compose myself now.

Pumpkin Brioche (with A Cinnamon Swirl)

I got my teeth whitened earlier this week. It was free, so I should’ve known better.
Besides the fact that I first had to endure the dental hygienist from hell (she gave me the most painful cleaning ever—and I usually never ever ever complain), I was put on the White Diet after the whitening. Your teeth are extremely susceptible to discoloration the 48 hours after, so you have to be very careful about what you eat.
If no one’s patented the White Diet yet, I swear I will. Here’s what Day One looked like: a white bread sandwich with mozzarella cheese and egg whites for lunch, a white bread sandwich with feta cheese and egg whites for dinner, and white bread toast topped with condensed milk (which isn’t actually white you see—it’s more a beige, which technically is still a no-no) for breakfast. I suppose none of those things are particularly healthy, but I was so afraid of eating anything not on the list that I didn’t really eat much at all. The worst part: no coffee! I walk away from this experience now knowing that I am extremely hooked on coffee and shouldn’t be allowed to operate machinery without it. In other words, it was really really hard to give it up, even for just a day. I wasted an entire morning being drowsy and sluggish, sitting in front of my computer unable to do any work.
The next day is easier since you get to drink really milky coffee with a straw, and your circle of food expands to beige and cream-colored foods. Thank god. I reverted to my usual fallback: cereal.
So that’s how I survived my white diet. I really shouldn’t be complaining though should I? I mean, I got my teeth whitened for free. My pearly whites are whiter! My smile more dazzling! My mouth looks 10 years younger!! Truthfully, the difference is negligible.

When I think about the things we do for beauty, like abstain from foods we love, I wonder where to draw the line. I mean, the whitening experience was a relative breeze compared to some of the crap people put themselves through. There was a time in my life where food was something of an enemy. Adolescence, you know.
Anyway, as you can imagine, this pumpkin brioche loaf would’ve been absolutely not allowed. Especially since the pumpkin turned its innards a light mustard-y yellow. It’s really really pretty, especially with the swirl (which I’m downplaying because it came out kind of squirrely-looking—but I’m including it in the instructions anyway because it really is delicious).
I had a bit of trouble with the dough. You know when you doubt a recipe and start tampering with it? Probably not the greatest idea when you’re dealing with something as delicate as brioche, which is this whole complicated ecosystem of ingredients. But I managed to salvage it, and it came out smelling richly of pumpkin and all its accompanying spices. It captures the taste too, but subtly. Don’t expect pumpkin pie. Instead, imagine soft and glorious air pockets, a thin, toasty crust, and a murmur of spicy pumpkin flavor. It’ll make a hell of a French toast this weekend. And I won’t have to worry about my teeth turning yellow.

Cinnamon Swirl Pumpkin Brioche
Adapted from Vermont Creamery
Makes 2 regular-sized (about 9″) loaves
For the sponge:
1/2 cup whole milk, room temperature
2 Tbsp maple syrup
2.25 tsp (1 packet) active dry yeast
1 cup AP flour
For the dough:
1/4 cup brown sugar, packed
2 tsp salt
1/2 cup pumpkin puree
4 eggs
3-3/4 cups AP flour
1/2 tsp cinnamon
1/4 tsp ginger
pinch nutmeg
pinch allspice
4 oz. (1 stick or 8 Tbsp) butter, softened
egg wash (1 egg whisked with a little water)
any combination of seeds
For the swirl:
4 Tbsp butter, softened
1/2 cup brown sugar
4 tsp cinnamon
Directions:
For the sponge:
In the bowl of a stand mixer fitted with the paddle attachment, mix the milk, maple syrup, and yeast. Let stand for about 10 minutes until bubbly, then add the flour. Mix until smooth. Cover and let rise until the sponge has doubled, about an hour.
For the dough:
To the sponge, add the brown sugar, salt, pumpkin, and eggs, and mix until incorporated. Switch out the paddle attachment for the hook attachment and add the flour and spices and mix until just combined. On low speed, add the butter, a Tbsp at a time, allowing each piece to be fully incorporated into the dough. Increase the speed to medium-high and continue mixing until the dough is shiny and starts pulling away from the sides of the bowl. It’ll make a slapping sound. If it’s not coming together, add flour, a Tbsp at a time, until it does. The dough’s going to be very sticky, so don’t add too much flour, only enough so it holds together.
Transfer the dough to a well-oiled, large bowl and cover it with plastic wrap. Once it’s doubled in size, an hour to two, deflate the dough, fold it in half (tucking the seam at the bottom), and let it rise again, this time in the fridge overnight.
The next day, let the dough come to room temperature, about an hour, then, on a lightly floured surface, cut it in half. It’s going to be sticky, but resist the urge to add too much flour. With each half, roll it out to the approximate width of your loaf pan (about 9″) and about double that in length.
For the swirl, use half the ingredients for each loaf. Combine the brown sugar and cinnamon. Spread the butter evenly across the surface of the dough, and sprinkle the brown sugar mix on top.
Starting on the short side, roll the dough into a tightly-packed cylinder. Pinch the ends and fold them under and into the bottom seam. With the bottom seam facing down, gently transfer the loaves into buttered loaf pans. Cover and let rise until doubled in size.
Preheat your oven to 400 degrees. Once the loaves are ready, brush them with the egg wash and sprinkle any seeds you’re using on top. Place them in the oven and bake for 10 minutes. Then reduce the heat to 350 degrees and bake for another 15 minutes, or until the tops of the loaves are golden brown and glossy.
Note: I actually baked my dough into one monster loaf and four large rolls, but the dough should be enough for two loaves.
